## Description

### Harvia Safety Switch: shuts the heater off if clothing lands on it

The Harvia Safety Switch is a black plate that sits above an electric sauna heater and monitors it while it runs. If a towel or piece of clothing lands on the heater, the switch turns it off. The heater stays off until the item is removed. The plate measures about 16 by 14 inches.

Made for electric sauna heaters, it connects to the heater’s control panel. You can also check it from a phone app. The box includes the device, its cable, and quick connectors. Want water added to the stones for you? See the [Harvia Autodose water dispenser](https://norsesteam.com/product/harvia-sasl1-sauna-autodose-water-dispenser/).
